Continued (2) 4.3 Vibration Step Stress Test The vibration step stress is conducted at an ambient temperature of+20 ° C. The vibration step stress of the tested product remains at the set point of 5GRMS vibration value, with an increment of 5GRMS and a 10 minute dwell time interval. After 30GRMS, the vibration decreased to 5GRMS to determine if a fault had occurred, and was not detected at higher vibration levels. If there is no fault in the detection of resonance vibration, the vibration will increase to the next level.
